Can you help me identify a vine, growing wild, with heart-shaped leaves, purple and white frilly flowers and oval green pods?
I would guess passionvine- Passiflora incarnata without seeing a picture. Here is an example. They have egg-shaped fruit loaded with seeds and a very detailed bloom.

From one small planting of a purple Passion flower vine, it has sprung up everywhere – rose bushes, yard, iris bed etc. How can we get rid of it permanently? When the vine is pulled up, it just comes back.
Even though it is a native plant, in the right conditions Passion flower can become a bit aggressive. The key is to learn to identify it when it germinates in the spring. Either pulling them and/or spot spraying with a glyphosate product can help to eradicate them. The longer they are allowed to grow, the more tenacious the root system. If you do want to keep one or two plants, be sure to harvest the fruit before it is fully mature to prevent any from reseeding.

I have your book “In the Garden”. The photo of the passion flower on the cover is beautiful and I would like to grow the vine on an arbor in our back yard. What conditions do I need to be successful? We live in Bella Vista. Will the plant overwinter here?
The native passion flower or Passiflora incarnata should do well statewide in full sun to partial shade. There are some improved cultivars with showier flowers. This past year the vines were literally covered in egg-shaped fruits which are loaded with seeds. Some gardeners find that the plants get a bit aggressive in their gardens. There is a red variety that is tropical and will not overwinter.
My husband found this strange weedy vine growing near the PV golf course and brought it home for my amazement. The interesting flower is sweet smelling and has a very unusual shape, I think. I’ll send another photo of the flower. Is the bulb the beginning of a gourd?
The plant is a passion vine and the fruit is edible, but full of seeds. The flower is the one on the cover of my book.
I am sending you a picture of a flower in my yard. Is it the same as the picture of the one on the cover of your book “In the Garden”? If so, what is it?
They are the same plant. The picture on the cover of my book is a passion flower Passiflora incarnate.
I have gotten multiple questions concerning the same plant, so thought I would put them all together for one question. Attached is also a picture of the plant. I found the attached flower growing on ground vine on my property. I’ve never seen anything quite like it and hoped you could identify it. It was about 2-2 ¼ inches in diameter. There is a seed ball on it . The bugs had eaten the leaves pretty badly . I would like to transplant a Maypop/Passion flower plant/vine from a field to my yard. When would be a good time to do so and do you think I would be successful in keeping the plant/vine alive? Would it be better to try to get seeds from the fruit and start the plant from seed? If so when do I harvest the seeds? The plant I found has beautiful flowers and fruit on it.
The flowers must really be popping now statewide, because I have gotten tons of questions about them this week. The flower in question is a passion vine, maypop, or passion flower Passiflora incarnata. The plant is perennial and will come back each season. In some parts of the state, they find it to be a bit weedy, coming up from the root system as well as from seed. They grow readily from seed; you can plant the entire fruit or remove the individual seeds and plant them. Allow the fruits to mature on the vine. They should turn a yellowish color when ripe. You could also transplant a plant this fall. Just flag the plants location now so you know where it is when it gets time to move it.
Botanic Notables: 500 Shades of Passiflora
Passion flowers are blooming! A genus of about 500 species of vines (and the occasional shrub), Passiflora flowers are distinguished by a characteristic design of radiating filaments and multi-leveled structure. They’ve long fascinated botanists, gardeners, and even theologians. We’ve designed a brief primer of several common features—the flower’s morphology, and how it gave the plant its name. By Anna Laurent
Summer is a time for lemonade, watering cans, and marveling at a beautiful oddity that creeps up our gates and fences—the passion flower. A genus of about 500 species of vines (and the occasional shrub), Passiflora flowers are distinguished by a characteristic design of radiating filaments and multi-leveled structures. While pollinators (thankfully) understand the beguiling flower, they often seem other-worldly to the rest of us. Passiflora have long fascinated botanists, gardeners, and even theologians. Recently, I’ve received passion flower photos from a couple friends who hope to know what’s going on with the strange flower. In case they’re not the only ones, we’ve designed a brief primer on the passion flower—the flower’s morphology and common features, and how those structures came to signify something other than “pollinate” and “fruit,” thereby giving the plant its name.

Morphology: A Beguiling Structure
The typical passion flower has five petals and five alternating sepals. While both are similar in size and color, the sepals are distinguished by a green hook, or awn, at the tip.
The corona is composed of thin, colored filaments that radiate around the central stalk. There are two layers, called the radii and the pali. The corona’s concentric rings of varying hues are thought to guide pollinators (insects and hummingbirds) to the nectaries at the center of the flower.

Three stigmas (female organs that receive pollen and direct it towards the ovary) extend above the ovary, where the fruit will be produced. Beneath the stigmas are five anthers (male organs that produce pollen). This arrangement, in which the stigmas are above the anthers, is a mechanism to avoid self-fertilization—there is less chance that the pollen will travel upwards to the stigma, than that it would float downwards and thus self-pollinate (most Passiflora cross-pollinate, though some self-pollinate). When the flower first opens, all anthers are initially facing upwards. Within an hour, the five anthers rotate downwards to face the flower’s operculum and corona—and thus the pollinators, who will be below, mining the nectar.
For bees to reach the nectar, they have to get through the operculum, a ring of dark fibers at the base of the central column. Arranged directly over the nectaries, the operculum filaments are a mechanism to discourage nectar robbers. The pollinator must penetrate the operculum barrier to access the nectar, and thus brush against the pollen-laden anthers. In the bee-pollinated P. caerulea, the operculum may serve to diffuse a fragrance emitted by the corona.
Fruits develop in the ovary. Most species develop elongated pods that are two to eight inches in lenght, and an inch or two in diameters. Not all are edible, and some are more popular than others. P. edulis (Purple Passion Flower) is arguably the most famous species. It produces the purple—or yellow—fruits that we commonly call “passionfruit.” It is cultivated in warm, frost-free climates throughout the world.
Etymology: From Whence the Passion
I always attributed Passiflora’s name to its oft-enchanting aromas and mesmerizing morphologies, evoking the passion of an unbridled summer dalliance. Not to dissuade those with similarly romantic associations, the truth is that the flower was named for something with a bit more gravitas—the Passion of Christ. In the early 1600s, Spanish Christian missionaries adopted the plant as a teaching tool, interpreting a Passiflora flower as a metaphor for Christ’s death. In this adapted theological model, the various flower parts each correspond with a symbol of the crucifixion.
Madonna & Child by Joos van Cleve, c. 1530-1535. A passion flower with a crown of thorns blooms from a carnation (detail). Art historians believe the passion flower was added years later, as the plant was not introduced to Europe until after the artist’s death. Why, and by whom, remain a mystery. Photo by: Cincinnati Art Museum.
The palmate leaves symbolized the hands of Christ’s persecutors; the tendrils were the whips used in the flagellation; the five sepals and five petals represented the ten faithful apostles (excluding St. Peter the denier, and Judas the betrayer); the five anthers signified the five wounds; three stigmas were the nails used to attach Christ to the cross; the layered radial filaments of the corona symbolized a crown of thorns. Linneaus would later name the flower for its theological translation.
An illustration of “Fleur de la Passion” includes a crown of thorns around the stigma. From Jardin d’hiver ou Cabinet dea fleurs, by Jean Franeau, 1616.

Passion-flower, any of about 400 species of tendril-bearing, herbaceous vines comprising the genus Passiflora (family Passifloraceae), with characteristic flowers. Some are important as ornamentals; others are grown for their edible fruits.

The wild passion-flower, passion vine, or maypop (P. incarnata) climbs about 3 to 9 m (10 to 30 feet) high and has pink and white flowers about 4 to 7.5 cm (1.5 to 3 inches) across and a yellow, berrylike, edible fruit about 5 cm long. The yellow passion-flower (P. lutea) is a smaller plant with greenish yellow flowers and purple fruits.
Some highly perfumed passion fruits are eaten as delicate dessert fruits, as the giant granadilla (P. quadrangularis). The purple granadilla (P. edulis) and the yellow granadilla (P. laurifolia), as well as the wild passion-flower, are widely grown in tropical America for their fruit. Passiflora maliformis is the sweet calabash of the West Indies. The size of these fruits usually does not exceed that of a hen’s egg, but that of the giant granadilla is like a gourd and may weigh up to seven or eight pounds.
The passion-flower blossom varies in form from a shallow saucer shape to a long cylindrical or trumpet-shaped tube, producing at its upper border five sepals, five petals, and many threadlike or membranous outgrowths from the tube, which constitute the most conspicuous and beautiful part of the flower, called the corona. From the base of the inner part of the tube rises a stalk bearing above the middle a ring of five stamens (the male pollen-producing structures). Above the stamens is the female structure, or ovary, at the top of which arise three widely spreading styles. Each style ends in a button-like stigma, giving an appearance rather like a large-headed nail. The ovary, with a single compartment, contains numerous seeds arranged in three groups and ripens into a berrylike or capsular fruit.

The passion-flower blossom is often used to symbolize events in the last hours of the life of Christ, the Passion of Christ, which accounts for the name of the group. Thus, the corona represents the crown of thorns; the styles represent the nails used in the Crucifixion; the stamens represent the five wounds; and the five sepals and five petals represent 10 of the apostles, excluding Judas, who betrayed Jesus, and Peter, who denied him three times on the night of his trial.

Why is my passionfruit vine not producing fruit?
You can expect fruit about 18 months after planting. If your vine is not fruiting after this time, it may be due to one of the following reasons.
- Passionfruit vines are heavy feeders and need plenty of water. A dry plant will not produce fruit, so ensure the soil is moist.
- Heavy rain during the flowering phase can ruin the viability of the pollen and cause a lack of bees for pollination. You can pollinate DIY-style using a small paintbrush to transfer pollen from one flower to another.
- Overfertilising results in flowers but no fruit. Passionfruit usually only needs fertilising twice a year, after pruning and again after fruiting.
- A fertiliser high in nitrogen promotes plenty of passionfruit leaf growth at the expense of fruit and flowers. Fertilise with compost, citrus foods, chicken manure or well-rotted cow manure. You can even put used teabags at the base of established vines, leaving them to seep into the soil as fertiliser.
- Passionfruit require at least five hours of direct sunshine a day. They should be planted in a sunny spot with no trees or competitive roots.
- Make sure you are pruning your vine correctly.
Why is fruit falling from the vine before mature?
This could be due to a cold snap or the plant not getting enough water. Passionfruit have a high water requirement when fruits are approaching maturity. If the soil is dry, fruits may shrivel and fall prematurely, so water frequently for short periods during dry times.
Why is the fruit empty?
Empty fruit on a passionfruit vine could be caused by overfeeding, particularly if you are using a fertilizer high in nitrogen. Compost, chicken manure or well-rotted cow manure are all better options. Make sure you water deeply at least once a week – the water should soak in through the extensive root system, encouraging passionfruit full of pulp.
Note that empty fruit could also be the result of inherent weaknesses in seedlings. If this is your problem, you may unfortunately need to start from scratch.
What type of passionfruit can I grow in Australia?
There are more than 50 varieties of passionfruit vine and many of them are suited to growing in Australia. These include Banana, Hawaiian, Norfolk Island, Yellow Giant, Panama Gold, Panama Red and Ned Kelly.
What type of passionfruit is best suited to a tropical climate?
The best ones to grow in a tropical climate are the Sweet calabash, Jamaican honeysuckle, and Sweet or Giant granadilla. The Panama Red is also ideal for a hot climate.
What is the best type of passionfruit to grow on a commercial scale?
Two species worth considering for large-scale growing are the excellent and hardy Nelly Kelly and the Super Sweet AV1 because it bears regular fruit and has good disease resistance (an important quality when growing on a commercial scale).
Why are the leaves on my passionfruit vine turning yellow?
Stop leaves from yellowing by feeding with a citrus food around the root zone two or three times between spring and late summer. Adding a sprinkle of Epsom salts to the watering can will also help.
How can I stop ants from eating the passionfruit flowers?
Ants hate strong odours so try planting ant-repellent herbs such as mint, pennyroyal, rue or tansy near trouble spots. Alternatively, keep ants away by sprinkling a trail of salt, cayenne or black pepper around the base of vine, or drawing a line with chalk to stop them climbing the vine to the flowers.
When/how should I prune my passionfruit vine?
Encourage growth by pinching out the top buds to promote side shoots. Growth should be from the graft section of the vine, not the rootstock.
Prune back hard in spring. Cut back one or two of the main stems to about one third of their length and trim the laterals, cutting out some of the denser growth completely. This allows better air circulation and fruit development in the following season.
After the second year, prune lateral branches once a year in late winter.
How often should I fertilise?
Overfertilising passionfruit results in flowers but no fruit. It usually only needs fertilising twice a year, after pruning and again after fruiting. The best seasons to fertilise are spring, autumn, and early or late summer.
What type of fertiliser should I use?
A fertiliser high in nitrogen promotes plenty of passionfruit leaf growth at the expense of fruit and flowers. Therefore, you are better to fertilise with chicken manure, well-rotted cow manure, citrus foods or compost. You can even put used teabags at the base of established vines, leaving them to seep into the soil as fertiliser.
When should I harvest my passionfruit?
Harvest passionfruit when they are fully sized and coloured – they are at their best when slightly wrinkled, so pick the fruit when the skins start to wrinkle.
How To Grow Passion Fruit
Passion Fruit (Passiflora edulis)
Passion fruit growing overview:
Passion fruit plants are fast growing subtropical-to-tropical vines that can produce lots of delicious fruit.
Passion fruit flower on left and freshly cut passion fruit on the right.
This article is focused on growing the purple variety of passion fruit (Passiflora edulis). However, many of the same principles apply to growing the yellow passion fruit variety (Passiflora edulis var. flavicarpa). The major differences between the two plant varieties will be noted in the article.

Passion fruit appearance:
- As you might expect the purple passion fruit is… well it is purple (at least when ripe).
- The fruit tends to be ovoid in shape and the fruit size ranges from 2-4 inches in length (a bit like a large egg).
- When fresh, the skin tends to be smooth and shiny, but begins to wrinkle in a few days. The skin is thick and tough which is great for keeping out the rodents and birds.
- Inside the fruit, you will find the delicious yellow-orange pulp surrounding many black or brown seeds.
- The yellow variety is… um, well it is yellow on the outside. The pulp is also yellow-orange for the yellow variety and the yellow passion fruit variety tends to be larger in size.
These are some of the larger passion fruit I have gotten (dime added for size reference).
Passion fruit taste:
- Purple passion fruit is delicious but the flavor is rather intense; like concentrated fruit juice.
- The yellow pulp is both sweet and sour with a very distinct aromatic tropical overtone. The tropical element is very distinct/unique but is reminiscent of a sweet guava. The fruit tends to become sweeter when the fruit is slightly shriveled. The seeds are hard and crunchy.
- The yellow passion fruit is more acidic, (more sour/tart), and less sweet than the purple variety. Some say that the yellow variety has an aroma that is less intense than the purple variety as well. The yellow variety also tends to have less juice.
Ripe and unripe passion fruit
Passion fruit use:
- A fresh passion smoothie is super delicious and refreshing. To make passion fruit smoothie, I blend passion fruit pulp with water, ice and a bit of dissolved cane sugar. The seeds get macerated in the blending process and sink to the bottom. Passion fruit pulp/juice is also a great addition to just about any mixed tropical fruit juice drink/smoothie. the tart passion fruit is a nice complement to sweet mango.
- Some people like to add passion fruit pulp to salads straight or added to dressings for a pop of bright flavor.
- My friend and colleague Dr. Philip has introduced me to eating it with watermelon which is delicious! Thanks Dr. Philip!
- If you like a more intense experience, eating the pulp straight out of the fruit is a gastronomical powerhouse of flavor.
- Bet it would be great on top of a muffin or a scone.
- Passion fruit ice cream sounds great too.
- Uncut fresh fruit should last a few weeks in a cool area of the kitchen without refrigeration.
- Please let me know your favorite passion fruit recipes in the comments section below.

Passion Fruit season:
- Passion fruit ripens about 2-3 months after pollination. In California, this typically means that the passion fruit harvest season is from the late spring to fall.
- The fruit drops to the ground on its own when ripe, which makes it really easy to know when the fruit is ready to harvest. This also makes harvest an “Easter Egg Hunt” like experience.
- In optimal conditions, passion fruit may start to fruit in one year. My growing experience is to get a handful of fruit in the first-second year of plant life and then lots of fruit thereafter.
Nearly ripe passion fruit is about ready to drop.
- This is a climbing vine which sends out long spiral tendrils that can hang on to all sorts of supports.
- The abundant deep green leaves are 3-8 inch long. Therefore, the plant can quickly provide privacy as it grows on a fence. The vine can also quickly cover an arbor/trellis. However, with that fast growth, the vine also requires training to keep in check.
- The plant can get heavy, therefore utilizing a strong support to grow on is important.
- The plant is also relatively short lived (5-7 years). Therefore, plant succession planning is an important consideration.
- Passion flowers are beautiful and add an exotic accent to a landscape.
- I think you can probably prune anytime you need to… and considering the fast growth of this vine, that is probably the most realistic option. Of course, removing dead and diseased plant parts should happen anytime you see it. However, some have advocated that in cool winter climates such as California, you should prune in the early spring. In warm winter climates such as Florida, some advocate to prune after harvest; which I honestly don’t understand because harvest time can be most of the year in Florida.
- Importantly, pruning or moving vines around during fruit development may result in fruit sunburn.

Sunburn fruit that has prematurely dropped (the yellow-brown area is the sunburn).
Passion plant growth speed:
- This is a very fast-growing vine that can grow up to 20 feet a year!
- In my experience, these plants tend to go through growth spurts in the spring and early summer. Growth slows down while fruiting and growth basically stops in cooler months.
Passion fruit vine taking over a nearby rosemary plant.
- I have my plants growing in rich sandy loam (this is basically well-draining rich organic soil mixed in with sandy soil).
- Excellent draining soil is critically important for these plants. Soil that is low in salts is also benificial.
- Check out my article on successful planting/transplantation for some additional helpful planting tips.
- Frequent deep watering is important and will keep your plants flowering for most of the year. This is not a drought tolerant plant and it is unforgiving of bone-dry soil. The plants require more water during fruit maturity and may prematurely drop fruit if water stressed.
- Growing passion fruit vines in containers is definitely possible, however, it may be challenging to keep up with the increased watering demands because the soil in containers tends to dry out fast.
- Passion fruit plants do best in full sun unless you live in an area that is really hot/dry. In hot and dry regions, partial sun is preferred.
- However, I have grown passion fruit vines indoors when I was living in a tiny Boston apartment. The plant did fine indoors and produced flowers although I never got any fruit.
Passion fruit fertilization:
- The intrinsic fast growth of the plant means that it will need more fertilizer.
- Fertilizing frequently is a much better option than hitting them all at once in one shot. Fertilizing 4x a year from early spring to late summer is my general timeline. I prefer not to fertilize in the winter because I don’t want to encourage young sensitive growth in the colder months.
- Some have advocated using a fertilizer with NPK of 10-5-20. However, I personally tend to recklessly and randomly use whatever fertilizer I have on hand and I have more fruit than I know what to do with. Looking forward to getting feedback on this one.
- In general, the purple passion fruit vine is a subtropical plant that does best in a frost-free climate. If they get hit by a frost they will likely loose leaves, and may even die-back to the roots. However, if the soil does not freeze, they may come back from the bottom. Therefore, don’t give up on them if you see massive die-back after a cold snap.
- Some varieties are more frost tolerant than others. This plant also does not grow well in intense dry heat. In general, this plant does well throughout Southern and mid-California up to the San Francisco area. The plants also seem to prefer the moderating effects of coastal regions.
- The yellow variety is more tropical, and is even more sensitive to cold/frost. Therefore, the yellow variety may do better in Florida than in California.
- Making the best use of the geographic orientation and the micro-climates of your yard may help keep to your plants at the optimal temperature range. For example, avoid growing your passion fruit vines in natural depressions in the landscape that can collect heavy-cold air in the winter. Growing on the south side of a building will provide additional reflected warmth and radiant heat; which can be good and bad. Extra warmth is great in the winter but too much heat in the summer can cook your plant.
- Frost cloth protection is another alternative but is challenging or this plant because of the large size of most passion fruit vines. If you use frost cloth, concentrate on covering the core and base of your plant. For more information about frost cloth and preparing for a cold snap, check out my article on the subject here.
Passion fruit flower from a side view.
Passion fruit flowers:
- Passion fruit flowers are wonderfully exotic, complex, and amazingly beautiful. A striking component of the flower is the numerous thin projections that radiate outward forming a sun-like corona.
- Unfortunately, the flowers tend to only last for one day.
- Below is a time-lapse video of one of my passion fruit flowers opening and closing in one day.
Passion fruit pollination:
- Purple passion fruit is self-fruitful (which means it can set fruit without needing a different plants pollen). In other words, you only need one plant to get fruit. However, the yellow variety is self-sterile (meaning it is sterile to its own pollen and incapable of self-fertilization).
- Apparently carpenter bees are the most efficient pollinator of passion flowers, however, I haven’t seen any visiting the passion flowers in my yard. Honey bees are also able to pollinate passion flowers. Although I have a lot of honey bees buzzing abound in the yard, I have only seen a few demonstrate any interest in the passion flowers. Therefore, because I have so much fruit, I can only guess that the minimal activity of honeybees is enough to do the job.
- Because the pollen is sticky and heavy, wind is not particularly helpful for pollination.
- The flowers can also be hand pollinated. I created a picture of key passion flower anatomy to help anyone interested in hand pollination (see below picture).
- The triple-branched light green structure at the top of the flower is the style. At the tip of each branch of the style is the stigma (see green arrow in the picture below).
- The five banana shaped structures surrounding the mid part of the passion flower are the anthers (yellow arrow).
- To hand pollinate, transfer the pollen from the anthers to the style. You can transfer the pollen with items such as a q-tip, watercolor paintbrush or small piece of cloth.
Passion flower anatomy for pollination.
Passion fruit propagation:
- Plants will readily grow from fresh seeds, and germination should take just under a month. Interestingly, I have noticed that different seeds from the same fruit will germinate at significantly different times. I have seen this with other plants and I believe it is an adaptation to increase the odds of survival (in case something bad happens to the environment during one random week and not another).
- I suggest planting the seeds about 1/2-inch-deep, although others have suggested 1-inch-deep.
- Passion fruit plants can also be propagated by cuttings and grafting. I am looking forward to hear your experiences and insight on vegetative propagation.

Passion fruit pests:
- Nematode infection is a major concern for passion fruit plants (See my article on nematodes here). The purple variety is more prone to nematode infection than the yellow variety. Some yellow varieties of passion fruit are to particularly resistant to nematode infection and therefore have been used as rootstock.
- Fusarium is a family of fungus, and some types can be very harmful to passion fruit plant roots. For example, the disease known as ‘base rot disease of passionfruit’ aka ‘fusarium wilt of passionfruit’ is caused by the organism Fusarium oxysporum f.sp. passiflorae. This infection will make a plant wilt and look like it is not getting enough water. Unfortunately, this infection can cause plant death in as fast as 4-14 days. Fortunately, I believe this is rare in the US.
- Disease prevention is always the best option. This starts with buying and promoting the growth of healthy plants through optimal growing conditions.
- Gardening tool sanitation is important for all of your plants and can help prevent the spread of many types of plant disease. Removing dead and diseased plant parts is also very important for overall plant health.
- Snails have been reported to be a big problem in some areas, sometimes being so bad to the point of killing young plants. Fortunately, I have not seen this myself.
- A great advantage of growing passion fruit (at least in my area), is that marauding rodents and birds seem to be oblivious to them. This in part is likely due to the fact that the skin of the fruit is thick and hard to get through without a knife.
- The purple passion fruit variety is native to South America (mainly Southern Brazil, Paraguay, Northern Argentina). The yellow variety is likely native to an overlapping warmer range in South America.
